Concept Flashback – RENNtech 2011 Mercedes-Benz GLK350 SPEC.R Hybrid Pikes Peak

glk semaRenntech won the Mercedes SEMA 2010 tuner challenge, and was awarded a little present as a result!

Another iteration of the concept -- but this time as a real rally car! All the enhanced aero is needed when climbing up to 14,000-feet at Pikes Peak International Hillclimb -- when the KW springs and new NITTO grip setup are also helpful.

The powertrain is a RENNtech-tuned V6 pushing 350HP, an increase of around 80 ponies versus the atmospheric petrol. Non-turbo at Pikes Peak is challenging, so the SPEC.R Hybrid adds a jumbo PHEV battery under the rear floor.

Finally, custom graphics from 3M wraps show off the style and the product in glorious fashion.
